Apple's AAC encryption cracked ... sorta

Linkage

Mr. Fair Use himself has written a little app that dumps the AAC stream of decrypted .m4p files to another file, creating a stream which is bare-bones AAC with no encryption or DRM at all. It's Windows-only, but he's been a true good citizen and released the source. This isn't a crack in the usual sense; he's simply saving the decrypted AAC stream to a file, which I don't think there are any provisions against.

I have downloaded the code and I am taking a look at how it works. So far it seems very simple. I will post details as soon I am done.

Figured out how it works. Apparantly the writer used a DLL to create a system hook. When the AAC file is played the DLL attaches itself to the process and writes the file. My only complain is the guy's programming practice is as convulated as the folks who wrote iostream.
